“十五”期间中国油气勘探进展及未来重点勘探领域

“十五”期间，中国油气勘探进入新的历史时期，勘探工作量与投资规模不断扩大，陆相盆地岩性地层油气藏勘探取得了突破性进展，中西部地区前陆冲断带勘探不断获得新的发现，叠合盆地中下部组合勘探成果不断扩大，成熟盆地精细勘探成效显著，近海海域勘探进入增储高峰期。至“十五”末期，中国石油勘探呈现出稳定发展、天然气勘探表现出快速发展的好形势，原油储采比明显提高。“十一五”期间，立足国内油气资源，加强断陷盆地富油气凹陷、大型坳陷型盆地大面积岩性地层油气藏、海相碳酸盐岩、克拉通大型古隆起、前陆盆地冲断带、海洋深水和非常规油气资源等七大领域的勘探，中国油气勘探仍然可以保持高速发展。图6参20

Petroleum exploration progresses during the 10th Five-Year Plan and key exploration domains for the future in China

During the 10th Five-Year Plan, exploration investment for hydrocarbons had been increasing. Great progresses were made on the exploration of lithologic-stratigraphic reservoirs in continental lacustrine basins. There were successive significant discoveries in the foreland thrust belts in western and central China. Outstanding achievements were from the middle and lower combinations of superimposed basins. Precise exploration turned out to be a productive tool in mature basins. The offshore discoveries were tremendous. By the end of the period, oil exploration was steady, and gas exploration was growing rapidly. The hydrocarbon reserves growth was in a new peak stage, and the reserve/production ratio was improved markedly. During the 11th Five-Year Plan, the hydrocarbon exploration will be developing rapidly. New discoveries will emerge unceasingly in seven domains: hydrocarbon-rich sags in rift-subsidence basins, large lithologic-stratigraphic reservoirs in huge depression basins, marine carbonates, large cratonic palaeohighs, foreland thrust belts, offshore deepwater, and unconventional oil and gas resources.
